NOTES: Federal transportation expenditures consist of Federal
Government direct spending only, excluding grants to state and local
governments. Details may not add to total and percents may not add to 100 due
to rounding. To eliminate the effects of inflation over time, the Bureau of
Transportation Statistics (BTS) converted current dollars to chained 2005
dollars. BTS used the Price
Index for Government Consumption Expenditures and Gross Investment as the price deflator. The price index figures were obtained from the Bureau of
Economic Analysis, available at
http://www.bea.gov/national/nipaweb/SelectTable.asp?Selected=N#S3. Previous
editions of this table used chained 2000 dollars, so this table is not
comparable to previous editions.
